Human Chitotriosidase Is an Endo-Processive Enzyme
Human chitotriosidase (HCHT) is involved in immune response to chitin-containing pathogens in humans. The enzyme is able to degrade chitooligosaccharides as well as crystalline chitin. The catalytic domain of HCHT is connected to the carbohydrate binding module (CBM) through a flexible hinge region. In humans, two active isoforms of HCHT are found-the full length enzyme and its truncated versio...
متن کاملClinical utility of chitotriosidase enzyme activity in nephropathic cystinosis
BACKGROUND Nephropathic cystinosis is an inherited autosomal recessive lysosomal storage disorder characterized by the pathological accumulation and crystallization of cystine inside different cell types. WBC cystine determination forms the basis for the diagnosis and therapeutic monitoring with the cystine depleting drug (cysteamine). The chitotriosidase enzyme is a human chitinase, produced b...
متن کاملImmunomodulatory Effects of Chitotriosidase Enzyme
Chitotriosidase enzyme (EC: 3.2.1.14) is the major active chitinase in the human body. It is produced mainly by activated macrophages, in which its expression is regulated by multiple intrinsic and extrinsic signals. Chitotriosidase was confirmed as essential element in the innate immunity against chitin containing organisms such as fungi and protozoa; however, its immunomodulatory effects exte...
متن کاملSerum chitotriosidase enzyme activity in patients with Crimean-Congo hemorrhagic fever.
BACKGROUND Crimean-Congo hemorrhagic fever (CCHF) is a public health problem in many countries. Chitotriosidase (ChT) is an enzyme secreted by activated macrophages that catalyzes the hydrolysis of chitin and chitin-like substrates. The goal of this study was to assess the relationship between serum ChT activity and mortality. METHODS ChT activities on the first day of hospitalization were an...
متن کاملThe relationship between chitotriosidase activity and tuberculosis
Chitotriosidase, secreted by activated macrophages, is a biomarker of activated macrophages. In this study, we explored whether chitotriosidase could be adopted as a biomarker to evaluate the curative effect on tuberculosis (TB). Five counties were randomly selected out of 122 counties/cities/districts in Hunan Province, China. Our cases were all TB patients who were newly diagnosed or had been...
